tl;dr: I don’t want C++ to limit what I can express efficiently. Some rules, such as ones that rely on interprocedural analysis of full call trees, are inherently nondeterministic (because an implementation gives up when fully evaluating a case exceeds the space and time available; a.k.a.

A cluster is just a pool of compute resources available to a customer’s applications. The agent is written in Go, has a minimal footprint, and is available on GitHub under an Apache license. This architecture affords Amazon ECS high availability, low latency, and high throughput because the data store is never pessimistically locked.

This approach can be expressed in more formal way by the following equation: where is the data available for analysis, is the space of a retailer’s actions and decisions, is an econometric model defined as a function of actions and data, and is the optimal strategy. This framework resembles the approach suggested in [JK98].
